T aZZ wwm it may concern:

Be it known that I, CHARLES STREIT, a citizen of the United States, and a resident of Cincinnati, in the cou'nty of Hamilton and State of Ohio, have invented certain new and useful Improvements in Sofa-Beds, of which the following is a specification.

This invention relates to folding lounges or sofa-beds,and especially to an improved means for uniting the stationary and folding frames, whereby they are more securely eoupled together and readily folded or unfolded without liability oi cutting or injuring the upholstering material.

My invention also includes certain peculiarities of construction and combinations of cal transverse section of the'unfolded frames before being upholstered. In this view the lounge-back is removed, and the view is in the direction of the lounge-head. Fig. 3 is a rear elevation of my improved hinge for uniting the stationary and folding frames, represented in the position it assumes When the lounge is folded. Fig. 4 is a rear elevation of the central portion of the back rails of the stationary and folding frames, Fig. 1, With the back removed, showing my improved means for looking the frames together when folded. In this view the latch upon the folding frame is shown engaged With the detaining-hook on stationary frame. Fig. 5 is an enlarged elevation of the locking-latch seoured to folding frame. In this view the lateh is shown as drawn out of engagement With its hook. Fig. 6 is a vertical transverse section through line w w of Fig. 4. Fig. 7 is an enlarged vieW in front e1evation of my improved hinge in the position it occupies when the lounge is unfolded to form a bed. A portion of the rails 'of the tWO frames united by the hinge are shown in trans- Serial No. 172.841. (No modal.)

verse section as seen in Fig. 2. Fig. 8 is a top view of the hinge as shown in Fig. 7.

' The stationary frame and folding frame are each composed of a baek rail and end rails, of equal Width, and a narrow front rail. The back rail of the stationary frame is indicated by A, and its end rails by A, and the narrow front rail by A The back rail of the folding frame is indicated by B, and its end rails by B. The front rail of the folding frame is indicated by B Both frames are provided with cross-slats 0, which are the supports for the upholstering-springs. These slats are let into grooves formed upon the inside of the longitudinal rails of both frames, and the top edges of the longitudinal rails A B and footrails A B are rabbeted at a b to furnish an offset,upon which the covering of the mattress is tacked down, thus avoiding the necessity for the upholstering-strips usually employed.

The cross-pieces b, in which the swinging pillow-supports D are journaled, provide the foundation for the mattress-cover at the head of the bed. The two frames when unfolded, as in Fig. 2, form substantially a spring-mattress box. The two together are upholstered precisely as though they were a single-mattress box. The same slats, c, that form the foundation for the bed-springs in frame B also serve for the seat-springs,wbich are placed upon the opposite sides of the slats. The front rails, A and B of both frames and the adj acent ends of the end rails, A B, are united by the hinge representedin Figs. 3, 7, and 8.

The hinge is composed of right and left members E, which are united together by the curved link F. Each of the members E have curved slots, which are concentric With the 1 hinge-pivots e, andfr0m the link F pins project into these slots and serve as stops to limit the play of the hinge members by coming against the ends of the slots, thus stopping the hinge in either the position shown in Fig. 1 or Fig. 2. The members E have feet e,turned at right angles to the upright portions. These are perforated to receive screws, which pass through. them into the,narrow front rails of the frames. The pieees E are alsoperforated with screw-holes, through which screws are passed into the end rails, thus securely holding the hinges in the angles formed by the front and end rails, and serving at the same time to firmly brace the end and front rails togethef and support, theflhinge en d 9f the folding frame when unfolded, as in Fig. 2. The pillow-snpports D are round iron rods bent into an open rectangular frame. The short ends of the open Side enter holes in the stnps Z), as shown in dotted lime, Fig. 2, in which view the one npon the leftis shown turned np as it is when the lonnge is unfolded, t support the pillow, and the one upon the"right baud side is turned down, as both are when the lounge is folded. In the finishedlounge thes are covered with ticking, a single pice of which is donbled over both frames and stitched aronnd them, so that both are united and move together, thus forminga continuons Support aeross the head of the bed when turned np. \Vhen the frames are hinged together, the opening between the front rails of the lonnge is covered with an upholsteringfabrie,v g,in the prevailing fashion. When thelounge is nnfolded, as seen in Figs. 2and 7, this.:ma. terial folds under the arched link F without being injured or out by the bingo, as is the" case with the hinges now in common use;

The lounge is Jocked firmly in the closed position, Fig. 1, by my lateh-fastening, Figs. 4, 5, and 6, which I Will now desoribe. The latch H is a fiat metal plate,which is pivoted to the outside of rail B by a screw, h. nlhe plate H has projecting from it a Iedge, h, which is perforated to receive a cord, I, Fig.

5, or strap I, Fig. 4,which extends above the seat, as seen in Fig. 1, by which the lateh is released and the folding seat -frame turned over. Ihe platehas also a hooked projection, 7L2, to receive the free end of a coiledspring, J which holds the lower .hooked end of the latchin engagement with hook K, which is;secured to the inside of rail A,and, extending above the edge of said rail, has its hooked end 70 projecting throngh a notch in the adjacent edge of the rail B. The spring J is secured to the rail B by its bent end and the staples j j, between this end and the coil of the spring. The tapering notoh in.rail B guides the frames truly together, and, in connection With the hook k, prevents any end movement of the folding frame upon the sta tionary frame when locked, thus relieving; the hinges from strain. The pins projecting from the. link F through the concentric slot in the hinge members E, in addition to supportingthefolding frame in either position,

.The legs bfl which support the outer edge of the frame when unf0lded, are seenred to the rail B in a position to come against the wood- "W1k of the back M when the lounge is folded,

as in Fig. 1, and they are finished to have the appearance of being a part o f the back.

What I claim as new is 1. A hinge for folding lounges, consisting of the right and left members E and arohed conpling-link F, the said parts E having slots boncentric with the pivot-pins, and the link F having pisprojecting froin it to traverse said slots when the parts are'pivoted together.

2; In a folding lounge, the combination of the stationary and-folding fraxnes, each composed of baek and end rails of equal width, and the narrow front rails, A? and 13 with the hinge composed of right and left membrs E,*and arched link F,eonneeting thetwo members and bracing the front and end railsto, gether, sbstantially as set fortin 3. The locking-latch for folding loungs, consisting of the hook-plate H, having perforation, as h, for the pivot-bearing, and having perforatedledge 71, to receive cord orstrap I and I, and spring J, thesaid latch being c0nstructed to be secured to the back rail of a folding frame, and held inengagement with the hook or pin npon the stationary frame by the said spring J, and is also secnred to the folding frame, substantially as shown and described.

4. The combinatioi1, substantially as specified, in a folding lounge, of the stationary frame A, A, and A and the folding frame B, B, and B, hinged to the said stationary frame, as ShOWD,. With the latch H, k, k, and 7L2, and the spring J, secured to the rail B of the folding frame, which has a notch in its meeting edge: wh-en folded, with a hook, K 7c,secured to the frame A and projecting aboxze the edgeof said frame and throngh the notch in fram B When the lounge is folded, substantially as shown and desoribed.
